my engine was bogging down so i replaced the inlet manifold gasket covering it all over with loctite no3 aviation non hardening form-a-gasket (great stuff)
made no difference still bogging the problem for me was the other end of
the inlet manifold tube is too short to push all the way into the carby
(it hits the weld at the bend) so i ground some weld off and put a o-ring
in the carby.
i've seen a couple of posts on both these mods with pics check em out
(full credit to these posts )
what i added is a strip of aluminium can under the clamp on the carby
i put a hole in it where the clamp locating lug is and made sure it was thight up against the shoulder and the joint was in the middle at the top took it off (after test fit)covered the inside of the strip with loctite aviation non hardening form-a-gasket put it on put the clamp on over it.
then i cut 4 strips of thick gasket paper and covered them with form-a-gasket
and pushed the strips into the slots in the end of the carby under the clamp and strip (cleaned the burrs out first) i then put a thin coat of form-a-gasket around the end of the inlet manifoldand inside the end of the carby put the o-ring in and pushed the carby on and held the pressure while i tightened the clamp now i have no more bogging down so it seems to work ok
in the photo you can see the black of the strip i used under the carby clamp and a peice of the gasket strip hanging out the top slot on the
opposite side of the carby.
i made an earlier post that probably made no sense without a picture about fuel leaking from the carby (my pics were too big to upload then)
in this picture you can see the fuel hose has an s bend if fuel starts running out an airpocket will form at the bend and fuel in the top half of the hose is trapped
making this bend tighter and closer to the carby will trap more fuel
